[ROOT] Chaining files together

Hi Everyone,

Currently, I am trying to loop over files and make chains. In PAW I would do:-

 MACRO run1
   do i=1,12
     chain run1 good_1999-b1-s0-r10B-on_all_[i].hbook
   enddo
   do i=1,57
     chain run1 good_2000-b1-s0-r10B-on_all_[i].hbook
   enddo
etc

I root I am trying to do something like 

TChain run1("h45");
for (Int_t i=1; i<13, i++) 
{
  run1.Add("/nfs/farm/babar/AWG11/Charmonium/Etac/ntp13/good_1999-b1-s0-r10B-on_all_[i].root");
}
for (Int_t i=1; i<58, i++) 
{
  run1.Add("/nfs/farm/babar/AWG11/Charmonium/Etac/ntp13/good_2000-b1-s0-r10B-on_all_[i].root");
}

Obviously [i] wont work here... Any ideas instead? I need to loop over
several thousand files in this manner. So a better solution would help a
lot.

Also a way to substitute the path
/nfs/farm/babar/AWG11/Charmonium/Etac/ntp13/ 
which is the same all the time would be good as well.

Thanks

-Phil
